Microfilaria are most numerous in circulating blood during the afternoon hours.

The two columns in the following floor framing plan support only loads from a gymnasium on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 12.9 psf acts on the tributary area of the columns. Combine this with the reduced floor live load, and then determine the total load that acts on one of the columns.

You have been tasked with designing a one-story building as a water treatment plant. The mean roof height is 15 ft, the roof angle is 20 degrees, and the effective wind area is 50 square feet. The basic wind speed has been provided by the local building authority and is 115 mph. Assume that exposure category B is applicable and that the building is not located on a hill or an escarpment. Also assume that the building is an enclosed simple diaphragm and that the building meets all five conditions listed in ASCE 7-10 section 30.5.1. Determine the positive net design wind pressure for h = 30 ft, pnet30, on Zone 2 of the Components and Cladding using the Simplified Envelope Procedure.

The two columns in the following floor framing plan support only loads from a gymnasium on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 11.3 psf acts on the tributary area of the columns. Combine this with the reduced floor live load, and then determine the total load that acts on one of the columns.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 7.30 psf acts on the tributary area of one of the purlins, determine the equivalent distributed load that acts on the purlin.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 7.84 psf acts on the tributary area of one of the sub-purlins, determine the equivalent distributed load that acts on the sub-purlin.

You have been tasked with designing a one-story fire station. The mean roof height is 20 ft, the roof angle is 15 degrees, and the effective wind area is 10 square feet. The basic wind speed has been provided by the local building authority and is 110 mph. Assume that exposure category B is applicable and that the building is not located on a hill or an escarpment. Also assume that the building is an enclosed simple diaphragm and that the building meets all five conditions listed in ASCE 7-10 section 30.5.1. Determine the positive net design wind pressure for h = 30 ft, pnet30, on Zone 1 of the Components and Cladding using the Simplified Envelope Procedure.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 11.78 psf acts on the tributary area of one of the columns, determine the equivalent point load that acts on the column.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 12.28 psf acts on the tributary area of one of the 50-ft girders, determine the equivalent point load that acts at the center of the girder.

A dead load of 9.5 psf acts on a roof with a 2/12 inch/inch pitch. Determine the equivalent flat-roof load.
